(54) BIOSENSOR CAPSULE AND SYSTEM


(57) A biosensor system has a capsule (1) with a housing configured for ingesting in a mammal GI tract, being cylindrical with domed ends. The housing forms an external space akin to a "cut-out" shape with two opposing transparent walls (6 and 7) facing each other in the longitudinal direction and a base wall (5) facing radially. An LED emitter (21) emits at a number of wavelengths in time sequence, and radiation is detected by a photo-detector (22) via the wall (7) which forms a concave lens. An antenna (60) is for wireless transmission of data to an external device and is in the form of conical spiral in an overall conical shape, located for optimum space efficiency in a domed end (8). A battery compartment is at the opposed end of the housing, separated from the antenna (60) by the external space (5, 6, 7).
